Abstract (en)

[origin: US2008041145A1] An indicator device is for sensing a valve of a fluid machine including a casing having an interior chamber, a valve controlling flow into the interior chamber, and a rotatable shaft configured to displace the valve between open and closed positions when the shaft moves between first and second angular positions. A first indicator member, preferably a pinion gear, is coupled with the shaft such that angular movement of the shaft angularly displaces the first member. A second indicator member, preferably a rack gear, is coupled with the first member such that the angular displacement of the first member linearly displaces the second member. The second member linear displacement is generally proportional to angular displacement of the first member. Further, a sensor is configured to sense at least one of linear displacement and linear position of the second indicator member so as to sense the position of the valve.
